I just moved into an apartment where a public wifi network is included in the price of rent. I want to add my router to the existing router in order to created a sub network that will be secured behind my password that I assigned to my router. This network needs to be secure because I discuss other peoples (and my own) sensitive medical information online. I have used multiple routers in the past a long time ago and can't remember the specifics other than the wireless radio channel of the 2nd router may need to be changed in order to eliminate interference, (especially in this case since both routers are the same manufacturer / similar models).
Is there anything else I'm not thinking of that needs to be considered for this installation. This is a new landlord that may not be to willing to let me go back to make changes, or multiple changes. It needs to be done correctly the first time...
Thanks,
Mike

You need to attach your router WAN port to an LAN port on the main router and use the main router IP address as your gateway on router 2 in order to pass the traffic to the main router that will get it to the Internet. Your wireless will be set up on your router with its own security, password, etc. and will be a different subnet than the main router. You will want to use a different radio channel of course to prevent interference (best to select a non-overlapping channel from 1, 6 and 11 if you are using 2.4GHz).

HERE is a brief guide that has a picture of what you want as a link in red text. They refer to the main router as the front router. Your router is the shielded router.

I don't quite understand "non-overlapping channel from 1, 6 and 11".
There are six routers in range of mine. Mine is on channel 1 with another (ATT supplied), two on ch 5, one on ch 6 and our main router that I am subnet from is on ch 11.
I've tried changing to channel 8 or 9, but it won't change. How do I know whether or not I am using 2.4GHz.
And by ch "1, 6 and 11" does that mean I can only use these channels if I am using 2.4GHz?

I'm thinking I will not have any interference issue since the main router is on ch 11 and mine is on ch 1, but I was trying to change it to a channel that no other router is on (routers on 1,6 and 11 already). No luck with that so far...

Thanks RealBeast for the help!

I'm sorry, I guess I could have mentioned that I have it connected per your instructions and it is working fine.
My map is HERE

I was only wandering about the not being able to change it to it's own channel, such as 8 or 9.

On the 2.4g band what is called a channel by the router is only 5mhz wide. The 802.11 standard uses 20mhz channels. So you actually are using 4 channels even though you put in only 1 number. Rather than explain this all the time it is recommended that people only use 1,6,11 to avoid overlap.

If you use say channel 8 you are overlapping the top of the group picked by people who are picked 6 and the bottom of the group of the people who picked 11.

Unfortunately it is even worse since many routers now want to use 40mhz (the ones that claim 150m or higher). This uses about 8 of the 5mhz channels. There is only 60mhz total bandwidth on 2.4g so really only 1 person can run 40mhz channels without interference.

This is why many people are going to 5g since their are more channels and they are 20mhz wide ....unfortunately 802.11ac is a pig and wants to use 80mhz or even 160mhz of the bandwidth so the trick of moving to 5g to avoid the neighbors router will not work for much longer.

Great! And with those channel numbers you are on 2.4GHz. Your channel of 1 is only minimally overlapped by 5 and sounds like the best choice for you with the other signals you have around. Your router guide will have a section on manually setting your channel if you need it in the future but you are fine for now.

To see what I mean by non-overlapping, take a quick look at the top couple of charts HERE and note that only 1-11 are available in the US.

As Bill001g said, sadly 5GHz will not be an answer for long for those who cannot use 2.4GHz due to the limited number of channels and the multi-channel use in 5GHz, plus some are not available near large controlled air spaces. None of that impacts you for now though.

Wow, this wireless stuff gets more complicated than I would ever have expected. So I'm glad I have help from you two guru's.
My wifi is working fine now and is secure, and file transfer within my 2 device workgroup is fine and too. So I thank you both for your help!
